Abstract: A microcontroller-based casino token counting system including one or more token bins comprising a casino dealer token tray suitable for receiving and holding stacks of tokens for the purpose of counting the tokens and calculating both quantities for each bin and total monetary values for all tokens in the dealer tray. Detection of token quantity in each bin is accomplished in various embodiments including Contact Image Sensors, Linear Image Sensors, and methods of converting both reflected light from each token, or detection of shadows cast by tokens using ambient casino lighting. Tray data from all bins is thus displayed to the operator, stored, and/or transmitted for the purpose of remote monitoring.

Abstract: A medication dispensing device comprising a housing having an enclosure configured to provide direct access to a current medication container storing medication to be dispensed. The device includes a plurality of bins, each bin configured to receive and store therein a medication container within a bin seat. Additionally, the device includes a scale assembly, within the housing, configured to automatically lift the medication container from the bin seat, weigh the medication container at least once and lower the medication container into the bin seat during a weighing cycle.

Abstract: A polyphonic electronic music synthesizer reproduces in real time complex sounds representative of musical instruments and other musical and non-musical sounds from an above-audio frequency signal. The synthesizer includes a sampling circuit for repetitively sampling the high frequency signal to thereby provide a series of samples, successive ones of the samples being produced by sampling the relatively high frequency signal at a rate of approximately once per cycle at instantaneous points in the cycle which are progressively displaced from the previously sampled points. A storage mechanism sequentially stores the samples, and a mechanism is provided for sequentially recombining each of the sample in real time to thereby produce the selected waveform at the desired audio frequency. Preferably, the sampling circuit is implemented digitally.
